通过水热法制备了球形、棒状和花形的纳米氧化锌;并利用原位聚合法制备了对应形貌的氧化锌/聚苯胺复合材料.用X射线衍射(XRD)、热重分析(TG-DTG)和扫描电镜(SEM)等测试手段,对氧化锌及复合物进行了结构表征.以次甲基蓝为模拟污染物,在紫外灯下考察了复合物材料的光催化性能和动力学特征.结果表明,聚苯胺(PANI)/氧化锌(ZnO)复合材料的光催化性能远高于纯纳米ZnO,而不同形貌的PANI/ZnO其光催化降解效率也不同,依次为球形＞棒状＞花形;PANI/ZnO(球形)的失水温度和分解温度与纯PANI相比分别提高了123.3℃和47.6℃.光催化动力学研究表明,以球形和棒状氧化锌为原料制备的PANI/ZnO复合材料符合一级动力学,PANI/ZnO(花形)复合物符合二级动力学.
